I'm trying to implement a Walt test of a nonlinear combination of a couple
of coefficients that have estimated on a loglikelihood function that I
programmed myself.

The problem is that my model has two equations, and I think the nlcom
command is having problems with the labelling of the variables:

. nlcom ((1/_b[eq1:bid2])*log(1+exp(_b[s:_cons])))

invalid name: (1/_b[eq1
r(198); t=0.02 21:42:55

Can anyone help?
